In section 126.96.36.199 the element h:selectManyRadio is mentioned as an example. I do not think this element exists but it would be better to replace it with h:selectManyCheckbox.
Sorry, this should not have priority Major. I don't see how (or if) I can change that.
Whew, thanks very much for catching that! That's embarrassing, since selectManyRadio is a contradiction in terms.
I'll change the priority to minor (I think Major is the default) and fix it for the next rev of the Tutorial.
Fixed in documentation source.
You are very welcome. I find the tutorial to be a great asset.
